Hi Danni,
Hindsight is a wonderfull thing, i've had lots of moments when I think about things i've done for/with my ex and now thing "doh...what were you thinking". He was on the large size (as am I) and when I'd loose weight in the past, suddenly he'd want to 'treat' me with meals, chocs, cakes "couldn't have me wasting away (and other guys looking) can we now" !!!!
Like you said, there's always a reason why they are ex's!!!!!
